Want to skip the classes and online group prep? Looking for a customized prep? Don’t despair! Flex prep is year-round tutoring ONLINE for the SAT and ACT.

We are offering SAT, ACT, or SAT/ACT Combo Packages consisting of

  • A Mindprint learning assessment
  • Six hour-long tutoring sessions
  • Two half-hour tutoring sessions 
  • Six optional practice testing sessions at home with Zoom proctoring on Saturdays


ACT FLEX PREP is available for the all test dates year round.
SAT FLEX PREP is available for the all test dates year round.
ACT/SAT Combo FLEX PREP is available for the all test dates year round*
*Recommendation: After the planning session, students book twice a week for six weeks: once a week for lessons, and once a week on Saturdays for proctored testing. The two half-hour tutoring sessions can be used to drill down on topics that need extra attention. Because of our tight summer schedule, tutor availability in July and August is limited. Book early for the greatest selection of appointments.

COST (per person):

SAT $1,253
ACT $1,258
ACT/SAT $1,289

Additional Tutoring is $150/hour if you have finished the package but wish to have additional instruction. If you want extended time proctoring on tests, there is a $25 surcharge per test.


It is important that the participants understand that the schedule is fixed, so plan carefully. You must book all of your appointments when you first purchase a package, but you can change the appointment yourself by opening the “new appointment” email and clicking the link that says “view appointment details”. Rescheduling on the website requires you do so at least two days in advance of the scheduled appointment. If you can not take the practice test on Saturdays, you may take the test at home on your own. To get an idea of the tutor availability, you can see Kate Dalby and Caroline Hesse’s schedules by clicking this link: Calendar.
After purchasing the package you should be able to book online by clicking on the purple “register” button and scrolling to the entry “test preparation tutoring“. Email Caroline Hesse at caroline@katedalby.com or Kate at kvs@katedalby.com
During the summer, all tutoring is Monday through Thursday; testing is once a week on TBD.    A full ACT or SAT takes 3 hours; students who qualify for extended-time testing need to discuss with us the best way to address the need for accommodations (there is a surcharge of $25/test for proctoring tests with accommodations).
